In this [Music Radar article](http://www.musicradar.com/news/guitars/u2-exclusive-the-edges-stage-setup-revealed-223342/10), the gear used by The Edge during U2's 360 tour is detailed.
The Edge's guitar tech, Dallas Schoo details his complex setup and pedalboards. The Edge's GE-7 is one of his "Outboard pedals", meaning it is not on his main stage pedalboard.

Billy uses a GE-7 in conjunction with a Hendrix Octavio Fuzz.

"Yep. Over my span of playing, I can’t count how many different ones I’ve run across. I used the [GE-7] graphic EQ pedal a lot. You’d turn the thing up and it’d give you the perfect overdrive, if you needed an extra boost. I [also] used the yellow OD-1 Overdrive. The DS-1 [Distortion], I have one of the original ones. It’s interesting…in 2007, I got to re-team up with Paul and go on a G3 tour. For me, that was pretty phenomenal, because it’s a Holy Grail tour for guitar, and I was just coming off of 10 years of not playing."

"Which pedal is that?
The BOSS EQ pedal [GE-7].
How are you using it?
I use it to boost my solos, to get more sustain and mid action. It’s amazing … things that once seemed hard or difficult to play just melted away and sounded so buttery with that pedal. If I’d known about that pedal a long time ago, I think my life as a guitarist would have been a lot better. I like how it adds just the right amount of punch to my solos, and not necessarily from distortion. For years I thought that was the only way. But now that I use this pedal, it’s like, “Where have you been all my life?” [Laughs.]"

Luke starts to talk about how he sets up and runs his pedalboard at 19:25 and starts with the Boss GE-7. "The only pedal that stays on 100% of the time is this EQ pedal - for just a little bit of mid boost at the end of your signal change."

We can clearly see a boss GE-7 (yeah, the guitar version) with all the sliders rolled back, probably for cutting the signal. Verification of this being Mike's board can be seen in [this image](http://cdn.mos.musicradar.com/images/artist-news/royal-blood/uk-rock-act-royal-blood-live-at-red-bull-studios-london-630-80.jpg).

Here's a picture of Robin Finck of [Nine Inch Nails](http://equipboard.com/band/nine-inch-nails) and [Guns N' Roses](http://equipboard.com/band/guns-n-roses), posing with his pedal board, including the Boss GE-7 on the top row, three from the left.

Fred used a Boss Graphic EQ pedal on his board. The item is listed in the gear that was stolen and shortly after returned. Here is a picture of him using it in his touring rig.

"I’m in Europe right now for a few weeks and this is the pedal board I’m running over here" - Pete Steinkopf from this [*Paste* magazine article](http://www.pastemagazine.com/blogs/lists/2012/05/14-guitarists-talk-about-their-pedal-boards.html). The Boss GE-7 is one of the pedals mentioned.

"Yeah, that’s really cool. I use it mostly for quirky sort of sounds, like if I want to get a special effect kind of sound. [Of course], you can use an equalizer to slightly shape [the sound as well], and I do that stuff, too."

“I think this is the most important pedal I have, because this is what will sculpt the tone. For my sound, I boost the bass a little bit, the lower tones, then I bring it up a little towards the mids so it gets a little of that high saturation. Then I just run that to the return of the amp.
“It can be a volume booster if you want it to be, but whatever rig I ever play, I’ll probably always try to run an EQ on it. You can hear where the bad things are, and just cut them out. You’re saving the sound guy some time by doing it.
“I find that a lot of times with high gain, once you get to saturation you’re really in a battle to hear notes – and you want it to be clear and crisp. This thing definitely helps sculpt the tone. I remember when I brought this to Eric and I said, ‘Listen, we need to run these’ and it just kind of changed the game for us.”

"Yeah. The EQ pedal is really used as a distortion boost. I use it when I’m [playing] at the top of the neck, [because the sound] quality of the guitar changes a little bit. It gets a little thinner. When you listen to Disco Biscuits’ music, I’m all over the neck. I play every single fret on the guitar twice at least every single night. My guitar is a 24-fret guitar, and I use every one of those frets up top.
When I get up there, I use the BOSS EQ to put a little bit more emphasis on those higher frequencies, and I also reduce some of the lower frequencies. When you’re up high and you have a lot of distortion on, you’re going to get some weird feedback coming at that lower range, so you want to dampen that lower range just a little bit. So, that’s what I use the EQ for.
Back when my clean sound was closer to a Wes Montgomery sound, I used to use the EQ to turn that sound into more of a classic Stratocaster sound. It was like a Stratocaster button! I’ve experimented with so many sounds over the years."

"…a key to my sound is a Boss GE-7 Graphic EQ that I use as a pre-amp. I set the volume on my amps low, and the volume on the EQ high, so I still get a lot of level out of the amps, but with less noise…"

Ok its not sexy to look at. In fact its probably the most boring looking pedal in the world. But its a versatile little sucker that can give you sparkle or mud at the flick of a slider. Very useful indeed.

After years testing one and another equalizer pedals, this one I'm sure is one of the bests. I did sell it and by a used japanese version witch I find a little better and less noisy, but I was happy even the new taiwan. This one can deliver a lot of volume /gain power with +15 db range, many possibilities to shape your boost and shape your solos and if you have problems dealing with bad amplifiers, using one of this can save your guitar sound.

For me this is the best Boss pedal. But it's main quality could be considereed as a deffect: it isn't a transparent equalizer! It adds color to the sound, apart from the very nice equalization. I use it with my acoustic guitar, but works very well with electric guitar, keyboards and even bass. Can also be used as booster... A must have pedal!

I think that 5 minutes with Boss GE-7 pedal is enough to convince any guitarist on Earth that this unit is an absolutely must-have on pedalboard. It's not an efffect, rather a tool, and a very helpful one, which allows you to shape your tone in countless ways. And that lovely boost feature! Your amp will shine in the mix with this pedal, believe me. I own an Orange TH30 head which is well know for fizzy gain channel and thanks to GE-7 I got rid of fizz and what I have now is pure, jucy, lush and heavy tube amp tone.
For that price (bought it for 40$ used) it cannot be beaten.

My amp/distortion/pickup combo makes for some harsh high end, so I needed something to take the edge off.

I replaced the bridge pickup in my Les Paul with a Seymour Duncan JB and I use a ProCo Rat2 for my primary tone. This combination mixed with my Fender amp makes for some really bright high end. I tried a bunch of different Overdrives and Distortion pedals to try to remedy the problem. Someone told me to just try an EQ pedal. Works like a dream. Ultimate tone control!
